Abstract:
Hypoxia, a condition of insufficient oxygen availability, occurs during normal development as well as tumorigenesis. Cellular responses to hypoxia are primarily mediated by hypoxia-inducible factors (HIFs). Recent studies have revealed that dormant hematopoietic stem cells (HSCs) reside within hypoxic regions of the bone marrow and that HIF is a critical player in HSC homeostasis. The functional significance of HIF in maintaining stemness also applies to cancer stem cells in hematological malignancies. These findings indicate that better understanding of the mechanisms underlying HIF functions in stem cells should permit the development of new therapies for tissue regeneration and cancer.

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
